Re: Reboot after power failure
From YDL's maillist I found the following snippet....
Pulled from a discussion about how to do the same on a PowerMac G4. I
don't own an XServe, so your mileage may vary, but it should work.
Got it :-) it can be done by simply by:
# echo 'server_mode=1' > /proc/pmu/options

Is it possible to set a macppc machine to automatically reboot
after power failure?
OpenBSD seems to have this working in OpenBSD 4.1:
"The OpenBSD/macppc platform now automatically turns the machine
back on following an unexpected loss of power."
Is it some sort of OpenFirmware thing?
There's a bit for it in nvram, Apple likes to call it 'file
server mode'. Not sure you can set it from OF.
How would I go about setting that bit?
A few lines in the pmu or cuda driver ( depending what mac you're
talking about ) should do it.. I /think/ we had code for it at some
point, probably set it on a few models that were intended to be
Anyway, this bit is managed by the onboard microcontroller ( cuda
or pmu, depending what model you have ) and thus can be set or
reset by sending commands to it. Shouldn't be too difficult to do.
Also, I'm not sure all models support it.
